Some of Latin America's most notorious dictators graduated from the military academy in Fort Benning, Georgia.

From Argentina and Chile, to Colombia, Guatemala and Mexico, there are few countries in Latin American untouched by the School of the Americas.

"Although the pretext for the war on people has changed - it used to be Communism, now it's the war on terror, the war on drug trafficking - it's the same people who are being affected and the same graduates … who are carrying out those policies of violence."

- Nico Udu-Gama, a School of the Americas Watch organiser

Based at Fort Benning in the US state of Georgia, the military academy has trained 65,000 Latin American soldiers over six decades.

And its roster of graduates who eventually came to lead their countries is impressive - were it not for the fact that they are considered some of the continent's most notorious dictators of the last century.

Overall, the School of the Americas has produced soldiers and generals responsible for the massacre and torture of tens of thousands of people across Latin America.

From among its infamous alumni are 11 former Latin American dictators including: Argentina's Leopoldo Galtieri, Rios Montt of Guatemala and Raoul Cédras of Haiti.

As it stands six countries have withdrawn their troops from the school; they are Argentina, Bolivia, Venezuela, Nicaragua, Uruguay and Ecuador.

"We have to hold that teaching process accountable by finding out what the [new] teaching manuals are. We know what our own country has done in terms of interrogating suspects in [the] war on terrorism; we don't think that that should be taught to other countries in Latin America."

- Peter Kornbluh, from the National Security Archive

But decades on from the Cold War, the school's influence is still being felt today: four of its graduates helped orchestrate the 2009 coup in Honduras.

Understanding such consequences requires little stretch of the imagination when considering what attendees were being taught

Training manuals that were used were declassified in 1996. They advocated the use of fear, payments of bounties for enemy dead, extortion, beatings and false imprisonment, as well as the use of truth serum.

The term "neutralisation" was also used - which the US department of defence has admitted is a euphemism for illegal execution.

Outraged at its programme, the US House of Representatives voted to close the school in 1999 but it opened almost immediately afterwards under a different name. Sixty-nine House members renewed the call for its closure in a letter to Barack Obama, the US president, last year.

This week, leaders of School of the Americas Watch, which campaigns for the permanent closure of the institution, went on trial in Washington DC on civil disobedience charges.

So we ask: What role does the School of the Americas play in Latin America now?

Joining Inside Story Americas, with presenter Shihab Rattansi, to discuss this are guests: Hector Aristizabal, a Colombian torture survivor; Nico Udu-Gama, an organiser from School of the Americas Watch; and Peter Kornbluh, a senior analyst from the National Security Archive.

FACTS ABOUT THE SCHOOL OF AMERICAS:

It was founded in Panama in 1946 with the stated objective of promoting stability in the region.

However, it soon acquired the nickname, the "School of Coups".

Under the terms of the 1984 Panama Canal Treaty, the School of the Americas was forced out of Panama and was relocated to Fort Benning in Georgia.

Under pressure from Congress it was officially closed in 2000; however the Western Hemisphere Institute for Security Cooperation was opened on the same site in 2001.

It currently trains about 2,000 soldiers from across Latin America and the Caribbean.
